3.3V Failure when installed in proto board
Posted: Fri Jan 10, 2020 8:05 pm
Hello,
I have a ESP32-DEVKIT-C that I am working on integrating into a prototype design. The prototype is being built on a simple 2 sided 0.1" grid breadboard with PTH solder pads. When I connect USB power or +5V to the main supply on a board that is sitting alone I get 3.3V out of the header pin as expected. I can install header pins into the receptacles mounted on the devkit and the 3.3V remains. However, when I install the header pins into my breadboard and attempt to conenct the devkit at that point, the 3.3V disappears. It appears to be short circuiting somewhere as the board gets very hot. This has happened with 2 devkits in a row. The breadboard is a DFRobot FIT0193. I measure open between all my pads, so I'm not sure why my voltage is disappearing and wanted to know if anyone else has run into this issue?
